Zenfone 5 Z lens problem

[vedatemre02]

I wanted to take a wide-angle picture, but I came across a trapezoid line on the screen and I was bored.
I think this problem is inside the lens
I looked at the camera and didn't find any superficial scratches. What is the problem?
Otherwise, I have to send my service, I wonder how healthy the service idea will be.
There is also a more problematic return.

It is clearly a cotton sewing thread cut.
It's not in your hand, like from a glove or anything else?
If it isn't, maybe it's in the gears of the camera. Only the service center can help you.
It's definitely not a software issue.
